' The Schedule refereed to in these Letten 4Patent: andmaking part ofthe same.

Tc all 'whom it may concern Be it known that I, JOHN TURNER, of Norwich,in the county of New London, and State of Connecticut,

have invented a newand useful Improveinentin Maaccording to myinvention.

'Figure 2 ,is a horizontal section of the same, in the planeindicated bythe line a; a: in iig. 1.

Similar'letters oreference indicate corresponding .parts in bothfigures.

This invention consists in'a'novel combination of l.strand-carryingdevices whichdo not twist the strands,

strandfcovering devices, and a laying-device, whereby fa number ofstrands isviirst covered, and afterward laid together into a oord. Y

By this combination, several important advantages are obtained overthose inachinesgin which the strands are twisted, covered, and laid atthe same time, among which may be mentioned-#- First, the use, for thestra-nds, of a cheaper material, siich as hemp, which cannot be spun ortwisted at the'same time that the covering is performed;

Secondly, the covering and laying of a greater length of cord, withoutlstopping to piece-np, owing to the greater quantity bf the strand, orbody-material, which can be worked in the machine at one ltime;

Thirdly, the reduction of' the compass of the ma chine, by dispensingwith the strand-twisting devices;

Fourthly, the provision made for the covering of strands of wire, andlaying them into a cord.

To enable others skilled in the art to make and use my invention, I-will proceed to describe the example of it represented in the drawings.

A. is the frame of the machine, in the centre of which is arranged, invsuitable bearings, the upright laying-spindle B, whicbhas rotary motionimparted to it, bybevel-gears a b, from the horizontal driving-shaft C,arranged in bearings -iu the lower part of the framing.

The upper part of this spindle is constructed with a laying-top, d, likethat of an ordinary cordage-machine.

VUpon the lower part of the laying-spindle there is rigidly secured adisk, D, in which is iirmly secured a number of spindles, E E,corresponding with the number oi-strands to be made into the cord,arranged parallel with theo 1 aying-spindle;` and between these spindlesthere is firmlyA secured, into tbe said disk, a corresponding number ofsmaller and shorter spindles,

c e, uponfwbich are placed loosely the rbobbins F F,

which carry the twine,g, or wire of which the strands are to becomposed.

Some distance above the bobbins F F, there is secured-firmly upon thelaying-spindle a disk, G, and to thisdisk there is firmly secured anumber of upright hollow studs, c, which are so arranged and constructedthat the spindles E E pass through, fit, and are held steady by them.

The exteriors of the said studs are turned to fit the central bores ofthe base-plates H H, of the hollow upright covering-spindles I I, whichcorrespond in number with the strands, and which rotate about theirrespective spindles E E.

These base-plates have each firmly secured in ita number of spindles,ff, upon which are arranged, one upon each, the bobbins J J, which carrythe silk or worsted with which the strands are to be covered, and whichis represented in red color.

Between the covering-bobbins there are secured to the base-plates H, ofthe hollow covering-spindles, upright guide-pins l l, to guide thecovering-material from its b obbin.

In the sides of the upper parts of the hollow covering-spindles I I,there are holes, corresponding with the number of bobbins, J J, on each,for the passage of the covering-threads to the strands; and above eachof the coveringspindles there is arranged a guide, fi,

secured to the laying-spindle, for the purpose of con-` ductingthe'covered strands to the laying-top d.

rIhe spindles E E h ave each, about opposite the middle of the length ofthe bobbins F F, a hole, h, made transversely through it, to serve as aguide for the strand, coming from its respective strand-bobbin F.

The upper parts of the spindles E E, commencing below the studs e, arehollow, and there is a hole, j, in one side of each, communicating withthe internal cavity.

Belowand attached to the base-plates H, of the hol` lowcovering-spindles, there are pulleys L L, the peripheries of which arecovered with India rubber or other soft *.material, and are in contactwith the interior of a stationary ring, M, which is concentric withth'e'main spindle.

The friction of these pulleys against the said ring M, caused by therotation of the laying-spindle B, produces the rotation of eachcovering-spindle upon its axis, as it revolves with and around thelaying-spindle.

Above the laying-spindle there is a take-up apparatos, which may be likethat common to cordage-v machines.

I will remark that this machine resembles that described for the samepurpose, in the patent to myself and I. E. Palmer', issued April 14,1863, except that the spindles E E are fixed relatively to thelayingspindle, instead of rotating upon their own axes, and, instead ofhaving strand-twisting apparatus, it has simply the bobbins F F, forcarrying the strand-ma.- terial.

The operation is as follows:

The machine being set in motion, the strand-material, which may beeither common hardware-twine, or any twine made for the purpose orotherwise, or wire, is unwound from the spools F, and drawn, by theaction of the takeup apparatus, through the guide-holes h audj, audthrough the hollow upper parts of the spindles E E, through the guides ii, and through the lay'llng-top d, above which they are laid togetherinto co The separate strands g, as they pass through the upper parts ofthe hollow covering-spindles, receive the covering which is wound uponthem by the rotary motion ofthe covering-spindles around them.

'I do not confine myself to the precise construction of the machineherein described; but

What I claim as my invention, and desire to secure by Letters Patent, is
